Be i-t known that'fl, ANQELO M. `Carro,

a subject of the otI-taly, a nd ;a resi dent of Phi-ladelphimin the countypoi'- Philadelphia and State ont' Pennsylvania,y have. `invented certain. `new and vuseful Improvey ments' in Filters, o f which-,the following is a specication. v

`The main Object'oi this "inventan site provide an effective y ,and GQ11511110.dQOULSf type of flterin whichzaseries of independentv containers, each adaptedftocontain lfilter-` ing vmaterial `of ditlerent grade or substanceare removably engagedandgnor-mally clampf i edy in operative posit-1on1 l, .1;

numeral 10 designates' vthe main .cylindrical body' l of the filter, the same resting upon feet 11. The upper body portion 12 vis eX-` panded and provided with a cap 14, secured by screws 15, clamping a ring or gasket 16 between the abutting surfaces, the cap having a knob 17 atits highest point by which it may be conveniently handled.

An annular chamber 2O is formed in the upper part 12 of the filter body, a co-operative opening 21 extending into the cap 14.

Entering the chamber 2O is a pipe 22, leading from a source of supply of the liquid to be ltered and. provided with a control valve 23.

Resting on the level bottom 25l of' the chamber 2O is a packing ring 26 secured 5y i 012111110 f ig'iQSerewed-into the' ,cliam ber -20'nearj1ts bottomand providedwith arms V28 `radia-t ing from the? raised center .291y squared.toueceiv'er wrench for adjust-f mathe/.clamp i lllterPOSed fbt-Weeliv 'the clamping: :ring ,27

Entering the` upper portionfof the cham` the chamber 43, is ano-therpi-pe 48 controlled.

by` a valvef49, thislatter .valve being yusedV to withdraw any sediment. that vmay form inthe chamber 43, -whilegthe pipel 46 deliversthe clear efliuent..l

.Ea-chg of theseveral baskets 31, 37 and are provided with `pivotedbails or handles 50, normallyturned level. with. their. respective- Hanges but ywhich lmay be raised when it is de siredtomanipulate the basketsin entering or i removing them.

The vuppermost .basket 31 isfyfilled Iwith.

relatively coarse filtering Amaterial 52 as lumps of charcoal, pebbles, etc., the intermediate basket 37 containing suitable media' 53 of a liner nature, while the low'ermost basket 40 contains the linest 54 of all the material used. 'In operation, the parts being assembled as shown, the valve 23 is opened, permitting the liquid to be lilteredto enter the cham-l ber 2O and pass successivelyy through the filtering materialv in the several baskets, eventually being deposited in the chamber 43, Where the clear leffluent may be lwithdrawn through the pipe 46 as required.

If it becomes necessary to inspect,'cleanse,

ioo

renew or repair the interior parts, the valve 23 is closed, cap 14 removed and clamp ring 27 unscrewed, permitting the several baskets and their contents to be withdrawn in an obvious manner.

Due to the use of cushion rings below the supporting flanges, the seats do not require machine iinishing, and neither doesv the interior of the body, thus making a filter relatively cheap to construct.

f lt will be apparent that the flow may be continuous or intermittent and, due to the inclined floor of the sedimentation chamber 43, should sediment occur, it is notroiled or disturbed by operating the outlet 46, but may be withdrawn through the pipe48.

Having thusdescribed my invention and set forth the Vmanner of' its construction, application land use, what l claim 'as-new and desire tosecure by Letters Patent, is

l; Alfilter comprising an upright body having a plurality of progressively contracted chambers therein, a sediment chamber ll (l in the base of saidbody having an inclined bottom, an inlet to the uppermost of said chambers, outlets farranged' at different heights in said sediment chamber, open meshed baskets in the intermediate chambers, said baskets containing filtering ma-4 kets in their respective chambers.

2. A. filter comprising an upright body having a plurality of progressively contracted communicating chambers therein in` cluding a discharge chamber having'va diagonally inclined bottom, a cap removably engaged over said body, porous baskets containing filtering material in each of the intermediate chambers, means for clamping said baskets therein, a controlled inlet to the l uppermost of said chamber, and controlled outlets leading respectively from the upper and lower portions of said discharge chamber.

3. A filter comprising a body having a series of communicating chambers disposed in the same axial plane, pervious baskets in the intermediate chambers, supporting flanges formed with said baskets, cushion rings set in the bottom of said chambers upon which said flanges rest, aclamp ring engageable with the flange on the uppermost basket, means for adjusting said clamp, and meansy for manipulating said baskets.

4, A filter comprising a plurally chambered body, a cap thereover, pervious basf kets in said chambers containing filtering material, annular flanges on the upper edges of' each basket upon which the bottom of the neXt adjacent upper basket rests, cushion rings below said flanges, an externally threaded clamp ring engaging the uppermost basket, means for adjusting said clamp ring, and handles pivotally connected to said baskets whereby they may be raised or lowered upon the remo-val of said clamp ring. v

5. A `ilter comprising `an upright body, aL cap secured over said body, said body containing an annular chamber extendingy into said cap, a controllable inlet to saidchamber,` av series 'of annular communicating` chambers below said inlet chambers, said second named chamber progressively decreasing 'in diameter, baskets disposed lin each of said series of chambers, a clamp ring removably engaged in the upper chamber adapted to maintain said basket in position, a sedimentation chamber inthe lower' portion of said body, said sediment-ation chamber having an inclined bottom, andl controllable outlets from said chamber, said outlets leading from the upper and lower portions of said chamber respectively, 1

6. A filter comprising an uprightbody having a plurality vof decreasing annular chambers axially arranged and in communication, the marginal edges of the chambers forming a succession of steps, open meshed baskets `suited to said chambers, annular outward flanges on each basket, said flanges being supported on the steps, `impervious rings over said flanges, and anexternally threaded clamp ring adapted to clamp said rings and flanges preventing the passage of liquid exteriorly of the baskets.v` v

In testimony whereof I have signed my name to this-specification.
